[LinuxBIOS] [PATCH] Initial support for the ASI/BCom MB-5BLMP / IGEL Winnet III

Wed May 9 01:54:59 CEST 2007

Here's a first patch for the IGEL Winnet III thin client. It allows me
to boot a Linux kernel half-way to the login prompt; at some point it
hangs, though, so more work is needed.

This is a 233 MHz Geode GX1 based thin client with Ethernet, USB, VGA,
a Disk-on-Chip, socketed DIP BIOS chip, a laptop-size RAM slot, a
normal-size (PC) RAM slot (don't remember the correct name right now),
and IDE connector, keyboard, mouse, sound, 2x serial port, parallel port,
1x ISA slot, 1x PCI slot. Fanless, extremely silent.

Ca. 20-30 Euro via eBay.

More details later, I'll write up a HOWTO for the wiki...

Attached is a boot log, and some lspci and other useful output gathered
from a Linux system booted using the original BIOS.

Uwe.
